Therefore, this study combines remote-sensing datasets (Sentinel-2 ASTER-DEM) with conventional data using Geographic Information System (GIS) analytical hierarchy process (AHP) techniques delineate potential (GWPZs). basin’s geology includes Pre-Cambrian rock units Arabian Shield southwest Cambrian–Ordovician northeast, Saq Formation serving as main aquifer. Six soil types were identified: Haplic Calcic Yermosols, Calcaric Regosols, Cambic Arenosols, Orthic Solonchaks, Lithosols. topography varies from steep areas northwest nearly flat terrain northeast. Hydrologically, basin divided into 28 sub-basins four stream orders. Using GIS-based AHP weighted overlay methods, GWPZs mapped, achieving model consistency ratio 0.0956. categorized excellent (15.21%), good (40.85%), fair (43.94%), poor (0%). GWPZ was validated by analyzing 48 water wells distributed area. These range fresh primary saline water, depths varying between 13.98 130 m. Nine wells—with an average total dissolved solids (TDS) value 597.2 mg/L—fall within zone, twenty-one are fifteen classified remaining fall TDS values reaching up 2177 mg/L. results indicate that central zone area suitable drilling new wells.
